As TD-SCDMA network is still in its initial stage

there are some inevitable outcomes such as weak coverage and coverage leak existing.Therefore

in order to improve customer perception and brand effect

so that those who in the edge of cell coverage and poor 3G signal areas do not have dropped calls and switch more smoothly to a better GSM coverage area

2G/3G interoperability has played a very great role as a bridge.Through this article

based on the optimization studies of 2G/3G interoperability

additional measurement parameters of 3 A event have been lead to

moreover

by means of case studies

in-depth study and research have been accomplished to the parameters

as well as suggestions made for parameters setting according to optimizing ideas of the mobile group.
